Error Prone Repair-Emphasis Weigle Reactivation

Abstract

There are several ways that living cells repair damage inflicted upon their genetic material (DNA) by ultraviolet light. The best understood, but by no means the only, type of photochemical damage is the dimerization of adjacent pyrimidine bases in the DNA chain, the most prevalent ones being thymine-thymine (TT) dimers. Almost certainly, we haven’t discovered all of the repair mechanisms present in cells. However, at present, three distinct types of repair are demonstrable;
